\section{Introduction}
%You should describe here global lighting models and talk about Whitted ray tracing, radiosity, Monte Carlo ray-tracing and photon mapping, explaining how they work and what they do. This description should be done mainly in words and not so much with maths. Also do not go too much into detail. The explanations should be done with the help of the 5 references above and you should cite these papers in the introduction. The introduction is concluded by a paragraph, that describes the structure of the paper like: "The first section is the introduction. In section 2, we discuss in more detail the techniques regarding (raytracing, Monte Carlo raytracing, depending of what you have implemented), which we have implemented. Section 3 shows some results that we have obtained with our implementation and benchmarks. The discussion and the outlook is the section 4."Length: about 3 pages . 

\section{Background}
%Here you describe the techniques you use in your code. Describe how you do ray-surface intersections, how you launch reflected and refracted rays, how you compute the intensities, what are shadow rays, etc. No C++ code. You may use pseudocode, but it is better do discuss the techniques only from a theoretical point of view. These descriptions should be accompanied by figures. The figures are numbered consecutively in order of appearance, each figure has a caption with a description and the figures are referred to from the text. Length: about 4-5 pages . 

\section{Results}
%Here you show results obtained with your code. You can do series of computations, where you vary the pixel resolution, the number of ray iterations, the number and type of the objects in the scene (transparent vs opaque) etc. You can compare in detail images computed from the same scene with different resolutions. It can be nice to discuss figures and effects in the figures, like color bleeding, noise, aliasing artifacts etc. You can list benchmarks (e.g. how long it took your computer to calculate a frame with a given resolution) in a table etc. Here you can be creative and look at things you like. 

\section{Discussion}
%Here you should repeat the key findings of your article and discuss how you could improve them. Do not go into details, but just give a general description. Do not use bullet point
